Abstract

The invention discloses a preparation process of a PVC architectural decoration film, which belongs to the technical field of architectural decoration, and can guide temperature control microspheres to be distributed on a film material by applying a magnetic field during calendaring in a manner of uniformly doping the temperature control microspheres into a PVC raw material, and adsorb the temperature control microspheres to the surface of the film material. After the film material is formed, the film material is absorbed and stored in a water spraying mode, the temperature control microspheres in the PVC building decoration film can be automatically modified after encountering high temperature, the hydrophilic characteristic in a normal state is changed into the hydrophobic characteristic; therefore pre-absorbed water is released, and after the water makes contact with the nitratine powder filled in the film material, the water is promoted to dissolve and absorb a large amount of heat; thus, the PVC building decoration film and a building are rapidly cooled, so that the external high-temperature influence is counteracted, the PVC building decoration film can be subjected to high-temperature protection, the service life of the PVC building decoration film is prolonged, and meanwhile, the building can be assisted in temperature adjustment to reduce energy consumption.

Description

technical field [0001] The invention relates to the technical field of architectural decoration, in particular to a preparation process of a PVC architectural decorative film. Background technique [0002] With the gradual improvement of people's living standards and the rise of the real estate industry, surface decoration materials have entered a period of rapid development. Among them, film materials such as PVC film, PET film and composite film are characterized by simple production processes, various surface decoration patterns and effects, and use methods. Simple and cost-effective, it occupies a dominant position in the new surface decoration material market. PVC film has good wear resistance, good corrosion resistance, high quality and low price, and is developing rapidly. It is widely used in indoor and furniture decoration, decoration industry, aircraft interior membrane, cabin membrane and other fields. It can make the surface of the decorated object obtain higher...
